The length of the altitude CH is 17.234.

Altitude of a triangle is defined as the perpendicular line segment joining the vertex to the opposite side.

The figure for the triangle is given below.

Here the area of a triangle can be found in two ways.

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

Consider the triangle ABC given below.

Area of the triangle when considered base as BC and altitude as AC is,

Area, A = [tex]\frac{1}{2}[/tex] × BC × AC

BC = AB Sin (50) = 35 sin(50)

AC = AB Sin (40) = 35 sin(40)

A = [tex]\frac{1}{2}[/tex] × (35 sin(50)) × (35 sin(40))

Area of the triangle when considered base as AB and altitude as CH is,

Area, A = [tex]\frac{1}{2}[/tex] × AB × CH

A = [tex]\frac{1}{2}[/tex] × 35 × CH  

Area of the same triangle will be equal when find in different ways.

[tex]\frac{1}{2}[/tex] × (35 sin(50)) × (35 sin(40)) = [tex]\frac{1}{2}[/tex] × 35 × CH  

Cancelling the terms which are on both sides,

CH = 35 sin(50) sin(40)

CH = 35 × 0.766 × 0.643

CH = 17.234

Hence the length of the altitude is 17.234.

Leo Gandolfi would save $54.34 by paying off the loan when the next payment is due.

What is percentage ?

Percentage can be defined as product of ratio of given value, total value and hundred.

To find out how much Leo Gandolfi saves by paying off the loan early, we need to first calculate how much interest he would pay if he were to continue making payments for the full 6-month term of the loan.

The total interest on the loan for the full 6 months can be calculated as:

Total interest = Total payments - Loan amount

We know the loan amount is $1,800, and the monthly payment is $310.50, so the total payments for the full 6 months would be:

Total payments = Monthly payment x Number of payments

Total payments = $310.50 x 6 = $1,863

Therefore, the total interest paid over the 6-month term of the loan would be:

Total interest = $1,863 - $1,800 = $63

Now, we need to calculate how much interest Leo Gandolfi would pay if he were to pay off the loan after making 4 payments.

The remaining balance on the loan after 4 payments is $612.34, so if Leo were to make one more payment, the remaining balance would be:

Remaining balance = $612.34 - $310.50 = $301.84

To calculate the interest paid on this remaining balance, we need to calculate the interest for one month:

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 12% / 12 = 1%

Monthly interest = Monthly interest rate x Remaining balance

Monthly interest = 1% x $301.84 = $3.02

Therefore, if Leo were to make one more payment, he would pay $310.50, which includes both the principal and the interest. So, the amount of interest he would pay if he were to pay off the loan after 4 payments is:

Interest paid = Total payment - Remaining balance

Interest paid = $310.50 - $301.84 = $8.66

So, by paying off the loan early, Leo Gandolfi would save:

Savings = Total interest - Interest paid

Savings = $63 - $8.66 = $54.34

Therefore, Leo Gandolfi would save $54.34 by paying off the loan when the next payment is due.

The two consecutive integers whose squares have a difference of 279 is 140 and 139.

The uninterrupted series of integers is represented by consecutive meaning in mathematics. It implies that the numbers are continuously following one another in a series. First, we must comprehend the idea of predecessors and successors in order to comprehend the consecutive meaning of consecutive numbers in mathematics. The number that is written immediately before the number is referred to as the predecessor. As opposed to successors, which refer to the number that follows the number. Think about the range 4, 5, 6, and 7. In this case, 4 comes before 5, while 6 comes after 5.

Let us suppose a number = x.

The consecutive number is given as (x - 1)

Two consecutive integers whose squares have a difference of 279, is given as:

x² - (x - 1)² = 279

x² - x² + 2x - 1 = 279

2x - 1 = 279

2x = 280

x = 140

x - 1 = 140 - 1 = 139

Hence, the two consecutive integers whose squares have a difference of 279 is 140 and 139.

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of the polynomial. The polynomial can be written as f(x) = (17/20)x(x - 5)(x - 8).

If the zeros of a polynomial function are 0, 5, and 8, then the factored form of the polynomial can be written as: f(x) = k(x - 0)(x - 5)(x - 8)

To find a polynomial function of degree 3 such that f(10) = 17 and the zeros of f are 0, 5, and 8, we can use the factored form of a polynomial. The factored form of a polynomial is the product of its factors, which are its linear binomials that correspond to its zeros.

For example, if a polynomial has zeros of 1, 2, and 3, then its factored form can be written as (x - 1)(x - 2)(x - 3). We can use this concept to find the factored form of the polynomial with zeros of 0, 5, and 8, which is:

f(x) = k(x - 0)(x - 5)(x - 8)

where k is a constant coefficient that we need to determine. We can use the given condition that f(10) = 17 to solve for k. When we plug in x = 10, we get:

f(10) = k(10 - 0)(10 - 5)(10 - 8) = 2k * 5 * 2 = 20k

Since f(10) = 17, we can set 20k = 17 and solve for k:

k = 17/20

Therefore, the polynomial function of degree 3 with the given conditions is:f(x) = (17/20)x(x - 5)(x - 8)

Answer: If the army regiment had 400 soldiers with provisions for 80 days, the food would last each soldier for 80 days / 400 soldiers = 0.2 days per soldier.

If 80 soldiers moved out, the number of soldiers remaining in the regiment would be 400 soldiers - 80 soldiers = 320 soldiers.

Since the amount of provisions has not changed, the food would last for 80 days / 320 soldiers = 0.25 days per soldier.

Therefore, the food would last the 320 soldiers for 0.25 days * 320 soldiers = 80 days.

4 4/5 miles

Step-by-step explanation:

2 4/5 = 2 + 4/5 = 10/5 + 4/5 = (10+4)/5 = 14/5

Proportions:

14/5 miles ⇒ 7/12 hour

A miles ⇒ 1 hour

A = (14/5 miles)(1hour) / (7/12 hour)

A = (14/5)/(7/12)

A = (14*12) / (5*7)

A = 168 / 35

A =  140/35 + 28/35

A = 4 + 28/35

A = 4 + 4/5

A = 4 4/5 Miles

The length of BD in the triangle is 24 units.

The triangles are similar by angle bisector theorem. The angle bisector theorem states that the angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle.

Therefore, let's find BD.

Hence, using the proportion,

12  / 20 = x / x + 6

cross multiply

12(x + 6) = 20x

12x + 72 = 20x

72 = 20x - 12x

72 = 8x

divide both sides by 8

x = 72  /8

The equation that represent the graph is C = 1.5m + 200.

A moving company charges a one time fee and cost per miles of it service. Therefore, the relationship is between the total cost and the number of miles.

Therefore, let's use equation to represent the relationship between the total cost C and number of miles travelled, m.

Hence, using slope intercept form

y = mx + b

where

Hence,

using (0, 200) (200, 500)

Let A be the given 2x2 matrix A = [1 2 ; 1 1]. To find a 3x2 matrix B such that AB = I, where I is the 2x2 identity matrix, we can use the hint provided: If B1 and B2 are the columns of B, then ABj = Ij. This means that for each column j of B, we need to solve the equation ABj = Ij. For j = 1, we have AB1 = I1 = [1 0]. We can solve this equation by setting B1 = [a b], so that AB1 = [a+b 1] = [1 0]. This gives us the system of equations a + b = 1 and a = 0. Solving this system, we have a = 0 and b = 1, so B1 = [0 1].For j = 2, we have AB2 = I2 = [0 1]. We can solve this equation by setting B2 = [c d], so that AB2 = [c+d 1] = [0 1]. This gives us the system of equations c + d = 0 and c = 1. Solving this system, we have c = 1.
